Richard Feynman, the iconic physicist and one of the progenitors of quantum computing, famously said in 1981: “Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d ...

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and ...

At JPMorgan Chase headquarters, a quiet quantum coup: the bank just beat Big Tech to a breakthrough in certified randomness—marking a rare win for Wall Street in the race to make quantum computing ...

Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

Over the past 50 years, astronomers have made dozens of major discoveries that help explain the nature and origins of the universe. They’ve measured the cosmic microwave background, or leftover ...
